Interface Tuple

The tuple is the main data structure in Storm. A tuple is a named list of values,
where each value can be any type. Tuples are dynamically typed -- the types of the fields
do not need to be declared. Tuples have helper methods like getInteger and getString
to get field values without having to cast the result.
Storm needs to know how to serialize all the values in a tuple. By default, Storm
knows how to serialize the primitive types, strings, and byte arrays. If you want to
use another type, you'll need to implement and register a serializer for that type.
